Question

x^4 +4/×^4.
pls answer it.​

Answer 1

Step-by-step explanation:

x^4 + 4/x^4 + 4 -4 ( adding and subtracting 4 we get )

x^4 + 4/x^4 + 4 *X/ X = ( x^2 + 1/ x^2) ^2

now

( x^2 + 1/x^2)^2 - (2)^2

( x^2 + 1/x^2 +2) ( x^2+1/x^2-2)

here ( x^2+1/x^2 +2 = ( X+1/x) ^2 and x^2+1/x^2- 2 = ( x-1/X)^2

so real answer is

( x+1/X)^2 *( x-1/X) ^2
